To visualise the beating heart and vasculature of a 72-hour-old chick embryo, ink is injected into its yolk sac artery with a finely drawn glass capillary needle. A window is cut into an egg to expose the embryo, and then the embryo is placed under a stereo microscope.
The result? A beating heart! And a complex vascular system, of course.

In 1961, Leonid Rogozov, 27, was the only surgeon in the Soviet Antarctic Expedition. During the expedition, he felt severe pain in the stomach and had a high fever. Rogozov examined himself and discovered that his appendix was inflamed and could burst at any time. With a local anesthesia, he operated himself to remove the appendix. An engineer and a meteorologist assisted surgery.
WOW.
